Study to Investigate the Safety of a Drug Called Osocimab at Low and High Doses in Adult Patients With Kidney Failure Requiring Regular Hemodialysis

Study Summary

In this study researchers want to learn about the safety of drug Osocimab at lower-dose and higher-doses in adult participants with kidney disease undergoing regular dialysis (a procedure that uses a machine to get rid of toxins and extra fluids in the blood). Patients with kidney disease undergoing regular dialysis are at high risk for heart and blood vessels diseases. Osocimab is a human monoclonal antibody under development for the prevention of events caused by blood clots like heart attack, stroke and death due to heart or blood vessels diseases. It works by binding to and blocking the activated form of clotting factor XI which increases the formation and stability of clots. Researchers also want to find out how drug Osocimab works in human body and how the body absorbs, distributes and excretes the drug. Participants in this study will receive monthly injection of either Osocimab at a lower-dose or higher-dose or placebo (a placebo looks like a treatment but does not have any medicine in it). Both Osocimab and placebo will be injected into the tissue under the skin of the belly. Observation for each participant will last up to 23 months. Blood samples will be collected from the participants to monitor the safety and measure the blood level of the study drug.

Primary Outcome

Cumulative incidence risk of the first Composite of MB and CRNMB (ISTH) at month 6 is reported in the table. Descriptive time to composite of MB and CRNMB Events is reported in statistical analysis. Descriptive time to composite of treatment emergent major and CRNMB events \[in alignment with International Society on Thrombosis and Haemostatsis (ISTH) guidelines\] analyses were performed. The cumulative incidence function for the event-of-interest together with the corresponding confidence int
